KalshiEX LLC v. Flaherty

No. 25-1922 Circuit · Decided


The Law · How the Case Works

Overview

Overview

KalshiEX, a CFTC-regulated prediction market, filed suit challenging the CFTC's authority to prohibit contracts allowing participants to bet on U.S. election outcomes. KalshiEX obtained a court ruling permitting it to offer election contracts; the CFTC's broader regulatory authority over prediction markets is at stake.

The Facts

Facts

KalshiEX sought to offer binary contracts allowing traders to wager on which party would control Congress. The CFTC initially blocked the contracts as involving gaming or involving activity contrary to the public interest. KalshiEX sued; the D.C. Circuit ruled the CFTC had not adequately justified its ban. The CFTC's authority to regulate political prediction markets remains contested.

The Issue

Issue

Whether the CFTC has statutory authority under the Commodity Exchange Act to prohibit election event contracts as contrary to the public interest, and what standard governs the agency's public interest determination.

The Rules

Rule

The CFTC may designate certain contracts as contrary to the public interest, but its determinations are subject to APA review; agency action must be adequately reasoned and consistent with statutory text -- the CFTC cannot invoke public interest as a basis to ban contracts without explaining how those contracts conflict with specific regulatory concerns.

The Application

Analysis

When the CFTC blocked KalshiEX's election contracts by invoking vague "public interest" and "gaming" concerns, the D.C. Circuit applied the APA's requirement for reasoned decision-making and found the agency's justification inadequate. The CFTC had not articulated how election wagering conflicted with specific regulatory interests the CEA empowers it to protect. Absent a rational explanation grounding its prohibition in the statute's text and purposes, the agency's action could not survive judicial review. The ruling thus constrains the CFTC's discretionary authority: the public interest standard operates not as a blank check to ban disfavored contracts, but as authority the agency must exercise through reasoned determination tied to identifiable regulatory concerns.

The Conclusion

Conclusion

Active. KalshiEX is operating election markets pending litigation. The case implicates the future of political prediction markets in the United States and the scope of CFTC jurisdiction.
